GRAIN-SHOCK SCOOP.

Application filed August 30,

T 0 all whom it may concern Be it known that I, FREDERICK GEssNER, acitizen of the United States, residing at Deep, in the county ofBottineau and State of North Dakota, have invented certain new anduseful Improvements in Grain-Shock Scoops, of which the following is aspecification, reference being had to the accompany-, ing drawings.

This invention relates to new and useful improvements in grain scoopingdevices and more particularly to a grain shock scoop and the primaryobject of the invention is to proscoop shocks from the ground and conveythe same to a member from which the same are dumped to a predeterminedpoint.

A further object of the invention resides in providing a device which issimple and durable in construction, inexpensive tomanufacture and onewhich will be very efiicient and useful in operation.

lVith these and other objects in view, the invention consists in thenovel features of construction, combination and arrangement of parts aswill be hereinafter referred to and more particularly pointed out in thespecification and claims.

In the accompanying drawings forming a part of this application, Figure1 is a side elevation of the device. Fig. 2 is a plan view thereof. Fig.3 is a vertical longitudinal section through the samea Fig. 4 is atransverse section therethrough as seen on line ei4, Fig. 1. Fig. 5 is asimilar view as seen on line 5-5, Fig. 2. Fig. 6 is a detail plan viewof the rear structure with the dumping member removed. Fig. 7 is adetail side elevation partly in section. Fig. 8 is a detail sectionthrough the forward end of the dumping member showing in detail theoperating means for the hinge section of the floor thereof; and Fig. 9is a detail side elevation partly in section showing a portion of themeans for actuating the endless elevator in connection with the forwardend of the device.

In describing my invention, I shall refer to the drawings in whichsimilar reference characters designate corresponding parts throughoutthe several views and in which 1 indicates a main frame, upon the rearend of which is suitably mounted the drive wheels 2 and upon the forwardend of which Specification of Letters Patent.

are suitably mounted the steering wheels 3. arranged in connection witheach of the rear wheels 2, is a sprocket 4:, over which extends anendless chain 5, said chain also extending over a similar sprocket 6carried on a rotating shaft 7, which is mounted transversely of theframe 1. This shaft 7 also has a sprocket 8 thereon, over which extendsa chain 9, said latter chain extending over a sprocket 10, carried on adrive shaft of an engine 11, the latter being suitably mounted on theframe 1. From this construction, it will be seen that as the engine isoperated, the rear wheels 2 will be caused to rotate and drive to propelthe device forwardly. A clutch mechanism, however, is arranged inconnection with this shaft which will permit the engine to be operatedor the device to be propelled, without affecting one another.

Suitably mounted to oscillate on the rear end of the frame 1, issubstantially a wagon body or what may be termed a receiving and dumpingmember 12. on the rear end of the member 12, is an end gate 13, ofimproved construction which, in the normal position of said member 12,is in its closed position and held locked by keepers 1 1, which receivetherethrough the free ends of rods 15 on the end gate. At one end ofsaid end gate is an arm 16, which admits of the raising of the end gateby hand, while at the opposite end of said end gate, is a tongue or lug17 which has a rod 18 pivotally connected therewith. The lower end ofthis rod 18 is engaged with a shoe or contacting member 19 carried onthe rear end of the member 12. From this construction, it will be seenthat as said member 12 is tilted, so that the rear end is disposeddownwardly, the shoe 19 will contact with the surface of the ground toraise the arm 18 and correspondingly raise the end gate 18. Thus, itwill be seen that as the member 12 is tilted, the end gate thereof willbe automatically raised so that the contents of said member may bedumped therefrom.

I have provided a means for automatically raising the dumping member 12and to this end, a shaft 20 is provided to extend transversely of theframe 1, forward of the engine 11. This shaft has connection with thedrive shaft by means of a chain 21,

-which extends over a sprocket on said en- Hingedly mounted gine andlast mentioned shafts and a pinion 22 on said shaft 20 meshes with arack 23 which is carried on the forward end of the dumping member 12 todepend from the latter. A clutch mechanism 24 is arranged in connectionwith the shaft 20 and the pinion 22, so that at a predetermined time,said dumping member may be tilted with the operation of the engine.

The flooring of the dumping member 1, at the forward end thereof, has ahinged section 25 formed therein, which forms a substantial gate or doortherefor. In the normal position of said member 12, this hinged sectionalines with the remaining portion of the flooring and I have provided ameans for raising this hinged section as the member 12 is tilted ordumped. To this end, an additional pinion 27 is carried on the shaft 20,which meshes with a ratchet 28 carried on and depending from said hingedsection 25. A clutch member is also arranged in connection with theshaft 20 and pinion 27, so as to dispose said pinion into operativeposition when desired and when so positioned and the engine is operated,said hinged section 25 will be raised to form a gate member for thedevice. This operation occurs upon the emptying of a load of shock orgrain into said member 12.

Mounted on the frame 1, forward of the dumping member 12, is arectangular frame 29 having a flooring 30 extending for a portion of thelength thereof and hingedly projecting from the flooring which isarranged on an inclined plane and arranged in series, are the tines orelongated teeth 31. The free ends of these teeth are disposed to pointsimmediately above the surface of the ground and are adapted to scoop upgrain and shock as the device is propelled. Operatively arranged on eachside of the frame 29, is an endless chain belt 32 which operates oversprockets 33 carried on the shafts 34 and connecting these chain beltsat certain points in the length thereof, are the cross members or slats35. One of the shafts 34 connects with a shaft 36 arranged on the frame29, through the medium of a chain belt 37 and when this shaft 36 isrotated, the chain belts 32 which, together with the cross pieces orslats 35 thereon form a carrier, are operated. This shaft 36 isconnected with the drive shaft of the engine by means of a chain 38passing over sprockets on said shafts, so that the operating parts ofthe device receive their source of power from the engine and a clutchmechanism is arranged in connection with the sprocket on the shaft 36 soas to throw the operating parts into and out of operative position, whendesired.

The front wheels 3 are mounted on substantially an arch member 40 andthe side arms-of this arch are loosely guided through bearings 41 on theside bars of the frame 29. Pivotally connected to the forward portion ofthe frame 29, at the sides there of, are the arms 42 and 43, the formerbe ing designed in the form of a bell crank lever and the free ends ofsaid arms are connected to coil springs 44, the latter be ing suspendedfrom the upper portions of said arch member 40. These arms 42 and 43 areconnected together by means of a transverse shaft and the arm 42 whichis substantially a bell crank lever has one end thereof connected to anoperating rod 46. The operating rod has pivotal connection with a lever47 which is fulcrumed on the rear of the frame 29. Through the operationof this lever 47, it is obvious that the forward portion of the devicemay be raised and lowered, as desired, and a ratchet and detent arrangedin connection with the le ver 47 permits the same to be retained in anyadjusted position.

The member which has been described as substantially an arch member 40,has the crown thereof pivotally engaged with the arms of the same topermit pivotal engagement of the arms with respect to said crown. Asuitable steering mechanism, such as is used in connection with motorvehicles and the like, is provided and arranged in connection with thearms of this arch member, whereby to steer the machine as the same ispropelled.

I have provided a means for cooperation with the endless elevator 32,whereby to permit the latter to run only at predeter' mined times, suchtimes being when a bundle or bundles are deposited on the teeth of thetines 31. To this end, a shaft 48 is mounted transversely of the frame29, to oscillate thereon below the upper reach of the carrier 32, andthe ends of said shaft are provided with crank arms 49 and 50. Connectedwith the crank arm 49, is a rod 51, which extends rearwardly anddownwardly along one side of the frame 29 and has pivotal connectionwith a bell crank lever 52, the latter being pivotally mounted on abracket or the like at the rear end of the frame 29. This bell cranklever in turn, has connection with a clutch mechanism 53 arranged inconnection with the sprocket 36. Carried on the shaft 48 are a pluralityof rods or arms 54 which, in the normal position of the shaft 48, dependfrom the latter to project over the tines or teeth 31. Thus as a bundleis deposited on the teeth of the tines 31, and the vehicle is travelingforwardly, said bundle or bundles will contact with the arms or rods 54to force the same rearwardly and up wardly and by so operating said rodsor arms, it is obvious that the clutch mechanism 53 will be turned toits effective position. As the clutch is effectively disposed, thesprocket 36.will be caused to rotate and correspondingly operate thecarrier 32. I have provided a means, however, for the retention of thearms 54 in their raised or effective positions, after the bundles havebeen drawn therebeyond, or through the rearward portion of the frame 29.To this end, an additional rearwardly and downwardly extending rod orshaft 55 is provided, the same having pivotal connection at its forwardend to the aforesaid crank arm 50 on the one end of the shaft 48. Therear-most end of this last mentioned rod or shaft 05 rests on a guide orkeeper 56 mounted on the side of the frame 29, adjacent the rear end ofthe latter, as clearly shown in Fig. 9 of the drawings. Mounted foroscillation in the side of the frame 29, immediately below the guidemember 56, is a shaft 57, one end of which is bent angularly as shown at58, to form an extension thereon, the same depending to a point betweenthe endless chains of the elevator 32 and immediately adjacent and belowthe lower rear sprocket 33, as clearly shown in Fig. 3 of,

the drawings. The opposite end of the shaft 57 projects outside of theside bars of the frame 29, and is designed to form a rightangularextension 59.

The extension 58 is weighted heavier than the extension 59, so as tonormally force the extension 59 upwardly and said extension 58, when inits normal position, is disposed in the path of the transverse bars 35of the carrier 32. As stated, the extension 58 is weighted heavier thanthe extension 59, so as to dispose the latter upwardly by a rocking ofthe shaft 57 in its bearings and an opening 60 is provided in the bottomof the guide member 56 to receive the one angular arm of the extension59 therethrough as clearly shown in Fig. 9 of the drawings. In thenormal position of the device, the rod 55 is adapted to rest upon theupper end of the upstanding angular arm of the extension 59, in aposition as shown in dotted lines in Fig. 9 of the drawings. WVhen theshaft 48 is rocked by the swinging rearwardly of the depending rods 54,the rod 55 will be drawn forwardly and dropped into a position as shownin full lines in Fig. 9 and thus raised behind the upstanding angulararm of the extension 59. The rod 55, with all parts connected therebywill be held in this position until such time as a bar 35 of the carrier32 strikes the extension 58 and upon striking the latter, the shaft 57will be rocked to swing the extension 59 downwardly, whereby to permitthe rod 55 to slide to its initial position and permit the shaft 48,with the bars or rods 54 thereon to also return to their initialpositions.

In practice, it will be seen that as the device is propelled, the tinesor elongated teeth 31 will receive thereon loads of shock and grain metin the path of the device. As a bundle is received on the tines or teeth31, and-the device is propelled, said bundles will contact with thedepending arms orrods 54 to force the latter rearwardly and upwardly andwith such operation of the rods, said shaft 48 will be rocked tocorrespondingly draw forwardly on the rods 51 and 55. The rod 51 will,obviously, throw the clutch mechanism 53 into its effective position andcause the elevator 32 to be operated. The drawing forwardly of the rod55 will dispose the same to a position as shown in full lines in Fig. 9and thus hold the bars 54 in their raised positions and also retain theclutch mechanism in its effective position. The shock and grain will beconveyed upon an inclined bottom of the frame 29 and passed to thedumping member 12. After a load of shock has been emptied into themember 12, the transverse bar 35 of the carrier 32 will contact with theextension 58 which projects in the path thereof and cause the shaft 57to be rocked in its bearings. With such rocking of the shaft 57, theextension 59 thereof will be disposed downwardly to permit the rod 55 toreturn to its initial position. With such a return of the rod 55, theshaft 48 will be again rocked to permit the rods 54 to return to theirdepending positions and the rod 51 will, of course, also be operated toreturn the clutch to its ineffective position. The carrier 32 will,therefore, be inoperative at such time. After such occurrence, theweighted end 58 of the shaft 57 will return to its initial position andcause the extension 59 to be forced upwardly so that the one arm thereofmay be disposed through the opening in the guide 56 and hold the rod 55in a position as shown in dotted lines in Fig. 9 of the drawings. Thedevice is then ready for another operation, such as above described.

When a sufficient amount of grain or shock has been emptied into themember 12, the hinged section 21 may be caused to swing upwardly throughthe operation of clutch member on the shaft 26, and at a predeterminedtime and place, the member 12 may be tilted so that the shock and graintherein are directed downwardly toward the rear end of the same. As thedumping member 12 is tilted, the end gate 13 will be automaticallyraised to permit the contents of the dumping member to be dischargedtherefrom.

From the foregoing it will be seen that I have provided a device whichis simple and durable in construction, inexpensive to manufacture andone which will be very efficient and useful in operation and while Ihave particularly described; the elements best adapted to perform thefunctions set forth, it is obvious that various changes in form,proportion and in the minor details of construction may be resorted towithout departing from the spirit or sacrificing any of the principlesof the invention.
